Partially; the GUI was bugfixed too at the same time(s). The 7.0.0.6 engine must
have been changed in several parts IMO compared to 7.0.0.2, because it behaves
very differently as tests have shown. Then, I think the castling bug (?) was
fixed with 7.0.0.8. The WM Test results contain detailed results for *4*
different Fritz 7, and indicate that 7.0.0.8 and the second version of 7.0.0.6
(there were 2) are virtually identical otherwise. There were also GUI-only
updates (i.e. the one which introduced UCI support did not contain a new engine
IIRC).

This rating list has kept the versions apart:
